Reference group for WC categories=normal waist group; reference group for gender=men.
Gender×WC=interaction effect between gender and WC.
p Values are from multiple linear regression models.
Model I: adjusted for age, education, income, employment, marital status and comorbidities.
Model II: adjusted for model I plus BMI category.
Model III: adjusted for model II plus an interaction term between gender and WC category.
BMI, body mass index; Coeff., regression coefficient; EQ-5D, EuroQOL-5 Dimensions Scores; WC, waist circumference.
